BAG- res'rnnnn.

Application filed July 14, 1921.

To all whom it may concern.

Be it known that we, JOSEPH BREZIN and Louis BERZON, citizens of theUnited States, residing at Philadelphia, county of Philadelphia, andState of Pennsylvania, have in vented a new and useful Improvement inBagFasteners, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, whichform a part of this specification.

Our invention relates to bag fasteners of the type used more especiallyin connectionwith hand bags. 7

Our invention has as its primary object the provision of a fastenerwhich may be readily unfastened to permit of the separation of theoverlapping frame members of a bagand which when the members areseparated will be automatically positioned to fasten the memberstogether again in the closing of the bag.

Further objects ofour invention are to provide a fastener which will beefiicient in operation and so constructed as to comprise a minimum ofparts, which may be readily assembled without the use of tools, andwhich when assembled will be proof against derangement and failure inoperation.

Heretofore the known types of bag fasteners have been open to theobjection that if they were so constructed as to be unfastened andremain unfastened until the bag was opened, it was necessary to fastenthem when the bag was shut, or if, on the other hand, they were soconstructed as to fasten by the'mere shutting of the bag, it wasnecessary to positively hold them in unfastened position until the bagwas opened. Either form of fastener is unhandy and troublesome to theuser, as in the first case fastening of the bag is frequently neglected,and in the second case opening of the bag is rendered difficult by thefact that it isnecessary in the ordinary bag to maintain two fastenersin unfastened position while the fastener incorporated with the lock isunfastened and in order to open the bag all three must be simultaneouslymaintained unfastened.

In accordance with our invention, the above described objections anddifliculties are eliminated and a bag equipped with our fasteners may bereadily opened and when closed will be securely fastened with onlySerial No. 484,534.

the necessity of merely unfastening the fee teners which then remainunfastened until the bag is opened, whereupon they are automaticallyprepared to securely fasten the bag when it is again closed, all ofwhich will ap car more fully hereinafter.

aving now indicated in a general way the nature, purpose and advantagesof our invention, we will proceed to adetailed description thereof, withreference to the ac companying drawings in which we have illustrated apreferred embodiment, and in whic'h- Fig. l is a view of the upperportion of a bag with fasteners embodying our invention attached.

Fig. 2 is aside elevation of a fastener em- Fig. 4 is a section on line4.'4 Figure 3.

Fig. 5 is a longitudinal sectional view of the fastener in fasteningposition. 7

' Fig. 6 is a longitudinal view similar to that of Figure 5 with thefastener in un fastened position.

Fig. 7 is an elevation of a modification of a detail of the fastener.

The casing a, provided with a slot 6 in one of its end walls, is securedto the overlying frame a of the bag 03 by means of lugs e, which extendthrough suitable slots in the frame and are bent over as shown in Figure5. The casing f is provided with side walls having elongated slots 9, 9near their lower edges and having their upper edges'bent outward anddownward to form L-shaped flanges k. The end walls of the casing f aremade of less height than the side walls. The casing f is adapted to besecured within the casing a by means of lugs 71 which extend from theside walls of casing 11 and are bent upwardly to engage the L-shapedflange k oneside with a lateral extension 11,, the edges of which arebevelled as shown in Figure 4:-

Positioned within the casing 7" adjacent to the locking member j is thebolt control-' 7 lingmember 1' having downwardly extendof casing f, andthrough the. slot 6 in casing a, and forms a finger piece, whereby thecontrolling member may be moved relatively to the locking member andthrough the aotion of the cam surfaces m, m and r, r efliect a raisingor lifting of the locking member p r The fiat bow spring 10 rests on theflange k of he locking member with its ends bearing against the underside of the top of easing a and acts to tend to keep the locking memberin lowered or locked position.

In practice, assuming the bag to be closed, the various parts will be inthe position shown in Figures 3 and 5. If now it is desired to open thebag, the extension t is pressed and the bolt controlling member movedrelative to the'locking member. The action of cam surfaces 7", 1" and m,m causes the locking member to be raised against the permit the lockingmember to assume its normal locking position under the influence of'thespring w. VlVhen the bag is again closed,the receiver striking thebevelled edge of the bolt lifts it, and when the bag is' fully closedthe bolt drops into the re ceiver.

In Figure 7 is disclosed a modified form a of controlling membercomprising a. round member 8 adapted to underlie the flange k on thelocking member and provided at one end with an extension 25 forming afinger piece. shaped extension 1) which, on the opening of the bag, isengaged by the extension to on the bolt receiver to return thecontroller to normal position and permit the bolt to be lowered byspring w.

Having now fully described our invention, what we claim and desire toprotect by Letters Patent is 1. A bag fastener comprising a boltreceiver, a locking member adapted to engage said receiver to lock abag, a spring adapted to act on said locking member and yieldinglyretain said member in looking position,

'member, to move and hold said locking cmember out of locking position,and a cam carried by said receiver acting, when said bag is opened, toshift said controlling member to permit said locking member to return tolocking position.

2. A bag fastener comprising a bolt receiver, a spring tensioned lockingmember adapted to be snapped into interlocking en- I gagement with saidreceiver to lock a bag, a controlling member in engagement with saidlocking member and adapted to be manually shifted to move and hold saidlocking member out of locking position, and a cam carried by saidreceiver adapted, when the bag is opened, to engage and shift saidcontrolling member to permit said locking member to return to lockingposition whereby, when said bag is closed, said locking member will snapinto engagement with said receiver.

In testimony of which invention, we have hereunto set our hands, atPhiladelphia, Pa, on this 11th day of July, 1921 piosnrn BREZINI LouisBERZON.
